Overview
The Microchip Technology AT24C02C-MAPD-E is a 2 kb serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) device. It communicates with the host controller using an I2C (2-wire) serial bus interface. This device is part of the AT24C0 series, which includes various capacities, but the AT24C02C specifically provides 2048 bits of memory organized as 256 words of 8 bits each. It is designed for low-power and low-voltage operations, making it suitable for a wide range of industrial and commercial applications.
